Railway alignments,
designed, checked, delivered.

Give it two points on a map. It finds the corridor, designs the geometry, checks it against your standard, and hands you the drawings.

Then you take over. Every point can be dragged in plan and in profile, every value overridden. The automatic pass is a starting point, not an answer.

Autonomous Corridor Routing from Two Points

01 — Workflow

Two pins in. A design package out.

Three steps. Everything between them is automatic.

Drop two pins

30 m terrain arrives for the whole corridor. Anywhere on Earth.

It designs itself

Route, curves, cant, grades, yards, bridges — then checks all of it.

Take the drawings

5 km sheets, DXF, LandXML, Excel, KML. Ready to issue.

02 — The economics

Fourteen weeks of drafting, gone.

Move the slider to your next corridor and see what it costs today.

Design cost avoided ₹8.5 L per 50 km corridor, first pass

How this is calculated

Conventional preliminary design effort, per route kilometre:

Corridor & options study0.30 d/km
Horizontal & vertical geometry, iterated0.45 d/km
Standards compliance checking0.18 d/km
5 km Plan & Profile sheet drafting0.24 d/km
Hydrology, catchments & structures0.14 d/km
Earthwork, quantities & reporting0.14 d/km
Fixed mobilisation4 d

RAD replaces the production effort with review: 1.5 days of setup and local input, then 0.09 d/km of engineering judgement, adjustment and sign-off. Figures describe a preliminary / reconnaissance design stage, not a detailed project report. Substitute your own rates — the model is written out above so you can argue with it.

03 — Proof

The problems that eat your week.

Solved on screen, live. Pick one.

Autonomous routing

The straight line is the one route you cannot build

A cost surface prices directness against side-hill earthwork, ruling gradient and curvature — then refuses to sit on water, settlement or worked ground.

A* over the DEM, 16 headings per cell
Water 350/m, plus 600 to cross a bank at all
Live OSM lakes, reservoirs, landuse, quarries & mines

Grade line

Earthwork you have to haul is earthwork you priced wrong

The finished line is shifted bodily until cut area equals fill area. A uniform shift changes no gradient, so nothing already designed comes undone.

Bisection to the level where the two areas meet
Tie-ins win — the shift tapers to nothing at a fixed level
Mass-haul balance lands in the Excel workbook

Compliance

It names the rule you broke, then repairs it and re-solves

Easing a radius lengthens the tangents and can push two curves into each other, so a repair is never one edit. It iterates until the design is clean or nothing further can be done.

40 rules over radius, spiral, cant, gradient, vertical
25 repairs, ordered — geometry before comfort
It stops where only a route or speed change would do

Crossings

Priced one lane at a time, every field road wants a bridge

Minor roads inside a 700 m window are clustered and diverted along a parallel service road, onto a single grade-separated crossing chosen where the fill already suits it.

700 m default consolidation window
Sited by fill — an underpass wants embankment, not cutting
Majors stay — a highway is never diverted

Station yards

A wagon left standing on a grade is a wagon that rolls

Every yard gets a plateau cut into the profile at the mean level of its own ground — flat, not merely legal — and the grade line is re-clamped either side so nothing it fixed gets steepened.
